What is an RWD file?

RWD files mostly belong to Windographer. RWD files are specialized data files that store system‐specific technical measurements and simulation results. They are not built on a common standard but are defined by the software that creates them. Typically, these files contain raw or processed data in a proprietary format such as binary or XML.
Key use cases:

• Wind data logs – Used by NRG Systems Windographer to record wind measurements for renewable energy projects. See NRG Systems.
• Rheometer data – Employed in RheoWin by Tainstruments for capturing material test data.
• Game resource data – Managed by TimeGate Studios as a Resource Warehouse Data File for game assets. Visit TimeGate for more details.
• FEA simulation results – Produced by Creo Parametric in an XML format to store finite element analysis outcomes. More information is available at PTC.
• Automotive sensor data – Used by Honda RWD Editor to store radar raw data for steering calibrations.

Functionality:
FilExt.com tip: The files serve as containers for detailed technical data, allowing the respective programs to analyze and verify measurements. Accessing the file properly requires the corresponding application that understands its internal structure.

RWD file extension format:

Every file has a defined file format, i.e. how the data is arranged in the file. The file format can be deduced from the file extension and the signature. File extension, signature and file format must match; otherwise errors will occur when the file is opened. Knowledge is power - this also applies when dealing with unknown or faulty files. Our analysis of the RWD files produces the following result:

The RWD file ending covers different formats for different programs. The file formats most commonly found in RWD files are:

• 45% of all RWD files start with the bytes 00 00 00 00 crucial for this file format. If you open these files in a text editor, you will see only illegible characters. The file size is in the range of 2 KB to 14 KB. The file type is old but is used even today. Certain words are almost always found in the files, such as NRG #40 Anem. m/s   m/s.
• 20% of all RWD files start with the bytes 88 88 00 00 E9 03 4F 4F 50 5F 48 41 44 45 53, which are crucial for this file format. These files are binary files, so they do not contain text, but only cryptic characters. The file size is in the range of 100 KB to 190 KB. The keywords OOP_HADES are typical for these files. Such files sometimes refer to qualification.

All other RWD files (35%) have no consistent format, often e.g. TimeGate Studios game data archive and XML. Tagged as rewards or speech. You can get all the details of your RWD file by dragging it onto this page or by clicking the button "Choose your .rwd file to analyze" above.
